Restoring HP and Canon printer cartridges (expired/NOS)

I wanted to get my Canon BJ portable printer and HP Deskjet 450 back up and running.

The HP is a bit "easier" to find working cartridges (but they are all expired)
  • Get a reliable refill kit
  • Add 1cc of additional fluid to each of the tanks
  • Place cartridges in a plastic container with a 70 (or higher) rated humidity pack (aka Cigar humidifier) and leave it alone for at least 2 weeks.

The Canon (actually an Apple Color Stylewriter 2200) is similar, but, for some reason, I have to leave it in the plastic container with the humidity pack for a month.
